Electromagnetic interferences from electric/hybrid vehicles

The use of high-power electronics to drive the electrical engines of the new electric and hybrid vehicles produces high-level low-frequency EMI. In hybrid cars, this new emission is added to the ignition system one. In this paper, some EMI measurements including current, near and far electric and magnetic field in two cars and a bus are presented. Some issues in the standards and tests setups must be updated: cars cannot be measured in idle state, new LISNs must be used in the high-power network, magnetic field evaluation for safety is mandatory in some vehicles or to consider radiated transient measurements.
